CHANGE OF MOVEMENT IN THE PELVIS DUE TO FATIGUE IN LONG-DISTANCE RUNNING- A CASE STUDY

Abstract

The purpose of this study was to clarify the three-dimensional movement of the pelvis due to fatigue in long-distance running. Four collegiate long-distance runners participated in this study as subjects and ran 4000m with a 5000m race pace. Subject D, whose running pace was significantly slowest, showed a significant decrease in stride length, stride frequency, and pelvis rotation angle at the end of the 4000m run. Furthermore, Subject D showed a significant increase in pelvis elevation. These factors suggested that to maintain the range of motion of pelvis rotation and to keep the pelvis elevation movement minimal is a very important factor in maintaining running speed and attaining high performance in long-distance running.
